Laser Marking Plastic Parts

By using laser radiation to develop a color instead of engraving the plastic damage from marking the target is minimized.

Laser marking plastic parts.

This application is typically used for permanent and durable marking of housings of all types relays switches plugs and other electronic components. Our plastic marking systems come in a variety of sizes so you can laser mark large parts one at a time or load the table with a jig of parts to engrave hundreds at once. Laser engraving involves physical removal of a section of the plastic surface using the laser beams. Direct ink printing puts an image on the surface of the plastic which can be removed by abrasion or solvents but laser marking can provide an indelible high contrast mark in the material itself with no direct contact with the plastic other than through the incident laser beam.

The polymer that the plastic parts are made up of dictates the methods used and the energy input needed to laser mark the plastic. The removal of some part of the material hence results in a cavity which comes in the form of a graphic or text as desired. Laser systems are the ideal choice when permanent high quality marks are required on parts during production. Advanced laser marking etching and engraving of stainless steel some plastic and ceramic parts.

It s been a reliable workhorse across a whole spectrum of industries for decades. Laser marking is fundamentally different from ink printing the traditional method of marking on plastics. As government and industrial regulations for clearly legible permanent marks and serial numbers on medical and aerospace parts increases laser marking laser etching and or laser engraving or scribing is rapidly growing in need. Generally the fiber laser generates a white mark on any plastic base color.

Laser marking technique is best suited for bar codes logos id codes etc. Welding use the heat of laser radiation to weld and join plastic parts. Laser marking is fast and maintenance free making it an attractive alternative to ink jet marking chemical etching or labels. Laser marking on plastic can be obtained with either a co 2 or a fiber laser source.

Laser marking of plastic or plastic engraving is a process during which components are labelled or marked with the aid of a laser. Laser marking expert q a. The co 2 laser is more often used for etching or engraving on the plastic. Color change in an injection molded part made of light plastic is brought about by means of carbonizing.

A fiber laser from epilog is the perfect choice for marking engineered plastic parts with barcodes serial numbers and logos.
